Tracking map of ten Black-capped Petrels captured at sea offshore Cape Hatteras, NC, and tracked by satellite.
Update (June 2020): we have finished tracking these Black-capped petrels and are now working on analyzing the data. This map shows the last locations of a Black-capped petrel we equipped with a satellite transmitter off Cape Hatteras, in May 2019.
The satellite transmitters being used are small solar-powered tags weighing 8 grams. They turn on for approximately 6 hours per day then turn off and recharge for approximately 28 hours. We thank the Migratory Connectivity Project for generously donating two of the satellite transmitters used in this study (shown in green on the map).
